The Owlery, where the school owls and the owls belonging to students live, is located on the top of West Tower.
The Owlery is a circular stone room, rather cold and drafty, because none of the windows have glass in them. The floor is entirely covered in straw, owl droppings, and the regurgitated skeletons of mice and voles. Hundreds upon hundreds of owls of every breed imaginable are nestled here on perches that rise right up to the top of the tower.
